This step concentrates the ore by performing the removal of impurities. It is also called ore dressing. This process is quite elaborate and is named according to the equipment or technique used. Let us take a quick look. Hydrolytic Method: In this method, the ground ore particles are poured over a vibrating table with a slope or inclination.

The article addresses a topical issue associated with optimization of dressing technologies and equipment for iron ore of nonstandard type and composition in operating and planned mines.

In some ore dressing plants, the crushing granularity is coarse and the processing ability of ball mill is low, thus influencing the system production capacity of the whole ore beneficiation plant. At the same time, the automatic degree of the system equipment is low and the power of the whole power grid is not high, so that energy conservancy and consumption reduction are even imperative.

Proper sampling methods, up to date laboratory testing, proper economic evaluations, and a collaborated effort between mining, geology, engineering and processing will result in a suitable design of the plant to extract the mineral from the ore body at an economically viable and efficient

extraction is done by leaching process using cyanidation method through a series of stirred tanks.
